is a frame like this any good? http://www.argos.co.uk/static/Product/partNumber/3354454/Trail/C%24cip%3D1500011615.Sports%2Band%2Bfitness%3EC%24 cip%3D1500011656.Home%2Bgym%2Bequipment%3EC%24cip% 3D1500011660.Boxing%2Bequipment.htm

Looks pretty good to me. Not a bad price either but here's one on ebay for cheaper:

This one has the advantage of a place for the speed bag. However, it doesn't look like it has places on the feet where you can put weights. And you're gonna need them when poundin' that bag!

Decisions, decisions eh!
