Hi mate
Buy a cocker
As a base level marker you will have an accurate, reasonably fast marker that over a period of time you can upgrade (electro frame, rex dialler etc) to become a paint slingin machine.
another option ( just to confuse you more) planet were sellin a standard 03 cocker fitted with an e-blade frame for a silly cheap price- defo the way i'd start.
try not to pay too much attention to hype, 20bps usually doesn't translate as that.
however ask any e-blade user and you'll see that some hype is genuine
