Toaster ovens are awesome. For a toaster oven, there are three key features:
- Big enough to fit the largest item you'll cook.
- Convection, so food cooks quickly and evenly.
- Enameled or stainless/aluminum interior. This lets you use harsh abrasives to keep it clean.
It's a given that your oven should have bake, broil, and roast modes.
For size, you'll probably want it big enough to comfortable fit a 1/4 sheet pan, or a 9" x 12" brownie pan. That will allow you to bake. Much bigger and it will take up a huge amount of counter space and realistically you should use a full oven for the big stuff. Too small and you'll have to fire up the full oven for everything, which defeats the purpose.
Convection makes a huge difference in toaster ovens; because they're so small, they are more prone to uneven heating than normal ovens, and leak heat out the front. If you open them to move food, they'll lose most of the heat, and take a while to get back up to temperature without convection. Convection lets you cook faster and more evenly.
For cleaning and long-term use, you need to be able to scour off the burned-on crap with steel wool or other harsh abrasive. Otherwise the oven will quickly become so unsanitary that it must be replaced, and nonstick finishes never last. The bottom will, of course, be lined with aluminum foil for easy cleanup of drips.
Oh, and rotisserie is a useless gimmick. I've had it on ovens, and never used it yet. Other people may have different experiences with it, of course, but that's my $0.10.
You probably have already purchased an oven at this point, but this video from America's Test Kitchen seems to explain a lot of things and offers some purchasing suggestions.
The model they recommend is the Breville Smart Oven, however it is made for the US and I could not seem to find a version made for 230V outlets. A reviewer suggested using a "step down transformer," but I don't have any experience with using US appliances in other countries so use your own judgement here.
If you've already purchased an oven, please let us know what you got and how it turned out! I find the idea of using a small toaster oven for heavy duty baking fascinating and would love to hear if you were able to make it work.

Any recipe which calls for you to bake, roast, or otherwise cook at a particular temperature, is expecting you to preheat the cooker to the specified temperature before adding the food, unless it specifically says otherwise.
"Roast" or "bake" never mean "microwave". If a recipe wants you to use the microwave, it'll say that. (There are, of course, things you can choose to do in a microwave or in some other cooker, like melting butter; that's up to you.)
