Here you go my man,
100 bucks, E1 frame with E2 board. Granted you are still capped at 15 bps in ramping but this gives you alot more flexibility that a flash and SF and it also gives you the option of going Tadao down the line. Or you could sell the E2 board for 80 and your SF grip for 40 and be only 50 short of a Tadao board. 150 and a bit of work and you will have all the options you want with the newest software available.
