• carfee if your on a tight budget, buy what you can afford and then upgrade accordingly. Yeah good deals are to be had, and knowing what brands to aspire to, have been good in the past, is cool, but only makes sense if you know what your looking for, and as you find on the forum one man's better than sliced bread, is another mans floating turd.
    my advice, check out the transmission thread for the most important bit of info you'll need for your bike, apart from getting the right sized frame, and that is getting a straight chainline.
    Take your bike to a bike shop, and get the info on the frame, if you don't know already, find out what bottom bracket you've got, what the threading is on it, find out the spacing on your rear dropouts, as the size of the rear hub, drives what length bottom bracket you need, and then you can figure out cranks/chainrings, so you get a good straight chainline.
    You'll see the brands that people use in the transmission database, quick search on the forum in the classifieds, or on ebay will tell you the costs and from there you can decide which is within your budget.
