I wish I had your problems! Me personally, I would keep it, as I find the moment I would need something like that, I wouldn't have it. But then again, if you don't think you'll ever have a need for it (ie, you have no interest in RF or complex audio work), selling it to someone who does would probably be the best option. Unfortunately, that won't be me; can't afford it. Good luck anyhow (and I saw your scope post earlier too - how'd you luck out with all that equipment?)...
