Ahh I've been researching for some time now!
I'm primarily after an M4 AEG, something mid-length. I especially want something with a slim M-LOK rail, 12/13".
BBGuns4less currently have this on sale:

I've heard not too bad things about DE on this forum, and for £230, it has everything I broadly want, and it has an ETU that'll do 1-5 round bursts.
I'd prefer something with a more modern receiver style, but with an ETU, you're looking at circa £400.
My wants, if you have any other suggestions:
SPR Length
M-LOK handguard
Metal receiver
Functional bolt catch
Programmable ETU
For my first RIF, I think it's a good price point.
It's £50 dearer everywhere else, I just want to get it in hand, and don't mind the drive and want to get a few other options in hand, maybe a pistol too, but I have no idea what, I'll just see if anything takes my fancy.
