I'd get the SSP18, light BBU, and plastic slide.
Run the piss out of it stock, then add the plastic slide and light BBU so you can get the most out of your money.
The HiCapa is decent, but I feel that at this point in the airsoft industry things have sort of caught up with each other. The SSP5 is supposed to be "THE BEST PISTOL EVER", which is also what Nov says about every gun he puts out, but that seems like a pretty solid option. I'd price out the gun, but also anything you'll want to buy for it later including mags, as pretty much everything Novritsch sells does the same stuff in slightly different ways.
