Hmm, I would say coming from nitro to electric, the techno motor mount and clutch would be more up your street really. Lots of motors to choose from that cost less than the Neus:
CastleNeu (mmm motor) will be here end of the month-ish = $100 or so.
Medusa 60mm motors are great, or the 70mm are coming soon too- $110-140.
Feigao XL motors- cheap, but they do the trick = $70-80 (get a clamp too ideally).
Hacker clones- from bidproduct.com 540 XL sized = $40-50 (trying one myself soon).
Megamotors - 22/35 & 22/45 sized = $100-190, depends on size exactly.
I think thats all the major ones covered really, any of those would do the trick, just match the kv rating to the input voltage, got some info on that in a FAQ I did:

If sticking to the nitro chassis, see about getting a motor mount brace that bolts to the underside of the chassis where the engine would normally go, helps stiffen the area up and reinforces the chassis.
