If you buy an Ego, for less than £200..I very much doubt you would bother selling it again would you?
Much better to keep it as a secnd gun.
I mean..I would love an 07, but I wouldnt sell my (rather sexy looking) XSV, because there would be no point...although that said...I doubt I would have many problems selling it for a reasonable price.
And your right about the Ego being the best...only other marker, would be a DM 5 or better...
