OK, it depends on what YOU WANT. Through personal experience, I have seen people progress better as bockers by getting the weight class designated to them and then upgrading the springs when they are ready - this does, however, result in greater costs. If you get a couple of classes up, you shouldn't need to replace them as soon, but it could slow your learning.
What could be a better way for you to decide, is to meet up with a local group and ask to have a go - i guarantee that they will be more than accomodating - this way, you can try a few sets, see what you like then go with that and you'll probably get some good advice on where to buy - I've never used amazon myself, but you may do better with a proper stilt company (eg. Pro-jump/7leagues) so you get a good guarantee etc etc.
