[Ethereum] Error: VM Exception while processing transaction: invalid opcode

I'm testing out the crowdsale contract from https://ethereum.org/crowdsale on a local testrpc and I can't figure out how to send funds to it. As I understand it, the anonymous fallback function receives the funds send to the contract. The sendTransaction method is not available directly on the contract instance, so I've tried out a few other options (and read the docs and done loads of googling).

Any suggestions?

Here's the javascript:

const cl = console.log; cl; // avoid lint error
// const Web3 = require("web3");

if (typeof global.web3 !== 'undefined') {
  global.web3 = new Web3(web3.currentProvider);
} else {
  // set the provider you want from Web3.providers
  global.web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
}

const web3 = global.web3;
web3.eth.defaultAccount = web3.eth.accounts[0];

var ifSuccessfulSendTo = web3.eth.accounts[1] /* var of type address here */ ;
var fundingGoalInEthers = 20 /* var of type uint256 here */ ;
var durationInMinutes = 10 /* var of type uint256 here */ ;
var etherCostOfEachToken = 0.2 /* var of type uint256 here */ ;
var addressOfTokenUsedAsReward = web3.eth.accounts[2] /* var of type address here */ ;

var browser_cs_sol_crowdsaleContract = web3.eth.contract([{"constant":false,"inputs":[],"name":"checkGoalReached","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[],"name":"deadline","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"beneficiary","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"tokenReward","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"","type":"address"}],"name":"balanceOf","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"fundingGoal","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"amountRaised","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"price","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"safeWithdrawal","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"inputs":[{"name":"ifSuccessfulSendTo","type":"address"},{"name":"fundingGoalInEthers","type":"uint256"},{"name":"durationInMinutes","type":"uint256"},{"name":"etherCostOfEachToken","type":"uint256"},{"name":"addressOfTokenUsedAsReward","type":"address"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"payable":true,"stateMutability":"payable","type":"fallback"},{"anonymous":false,"inputs":[{"indexed":false,"name":"recipient","type":"address"},{"indexed":false,"name":"totalAmountRaised","type":"uint256"}],"name":"GoalReached","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"backer","type":"address"},{"indexed":false,"name":"amount","type":"uint256"},{"indexed":false,"name":"isContribution","type":"bool"}],"name":"FundTransfer","type":"event"}]);
