I have an older Eclipse bag, and it is superb. That said, they are a LOT of wedge (as are many bags for paintballing) but that does give you properly designed compartments and pockets which suit what you're using it for.
I got mine off here S/H for £60, which I was happy enough to pay, but then again, I did manage a couple of seasons using a £20 roller bag from sports direct - it's only got to carry your kit after all! If you've got the spare cash it's worth having a proper bag, but not worth sacrificing other items for if you're on a budget.
