yea that's probably going to be your biggest challenge I see what you mean now about wanting a kit. You def want the ImmersionRC 600mW transmitter, there's a $10 plug and play cable for it and the iOSD Mini, which will run you about 70.
that's everything in the Phantom (except antennas, I'll get to that)
for a display you can go with the Black Pearl 7ch (not 32ch) or the Boscam/Neewer RX-LCD5802 which is a 32ch.
antennas are where you can do some shopping... the $110 FPVLR set of 3 is the best, but if you need to cut corner there you can get a decent set of antennas for like 50-70$. don't chince on $10-$30 antennas they're just not that good.
also you'll want a monitor mount for mounting the display to the RC, the Raveaerialvideo one is the best imo
good luck!
