thermo filters have a built in heater, the ecco's are small canisters and the professional come in 1,2 and 3. pro3 being the latest ones.
is your tank planted? if your aiming for the 10x rule you want a 2074,2076,2078, 28080,2180 etc, but they are big and quite expensive. if not after that much turnover go for a 2073 or 2075 i just picked one up on ebay used for £50. if you go on zooplus.de (make sure use german site) you can get a brand new 2075 with media for £130 which is a bargain as you get a 1st time buyer discount.
I'm not familiar with the 10x rule but yes my tank is planted. Also I need 1 fairly powerful as I've got a few plecos in the tank that leave a lot of mess that my 2 internal filters don't pick up plus they seem to get clogged very easily. I am looking at spending somewhere up to around £75 depending on how good the filter is but was hoping to get 1 for about £50/60
