Meeting with someone in a few hours - what rx should I buy?

[Dune]

Long story short, I'm meeting with someone to buy a JR 9303 heli model. He has a bunch of receivers, and I don't know if I should get one. The alternative is to pick up something like a Spektrum 6210 at my local hobby store. I need an rx for this weekend, so I gotta pick one up today. Thanks for humoring me

I'm flying a Naza / f450 for the time being with an eye to the future when I want to fly a quad/hex with gimbal.
Here's what the seller has:

-JR XP9303 Heli model. Has fixed wing and glider modes to...
-Upgraded Nimh 1650 transmitter battery.
-JR FM module on 48
-JR synthesized module
-XtremeLink 2.4Ghz module
-XtremeLink 8ch RX
-XtremeLink 6ch RX
-3 Castle Berg7p RX's
-Berg-5DSP 5 channel RX
-Berg microstamp
-2 GWS 4P FM RX's
-BlueArrow 5ch FM Rx's
-JR R700 7ch FM RX

What do you guys think? My finalists are JR R700, maybe theXtremeLink 2.4 + the 8ch rx. This is just going off the specs - I haven't heard an eval of their performance from anyone. I'm using a Spektrum 6210 borrowed from a friend for now, and it works fine, so that's the safe bet.

Thanks a ton,
Josh

i don't see a 2.4 rx like your asking...... everything is fm.... is the jr synthesisized mod 2.4? the extreme link thing is a module that fits the back of the radio like the jr one mentioned above

spektrum 6210 is 2.4
