Bill-
The 701, and now the 750, has been my LSA dream plane for quite some time now and I've been following the development of the aircraft. If you are willing to do a lot of the building, no pre-built 50% kits, and some creative scrounging, you may be able to build the 701 for around 30,000. The 750, maybe 45,000.

HOWEVER...
The differences between the 701 kits and the 750 kits are striking. The 750 components are CAD designed and NC cut. The construction fit is phenomenally good. It may well be worth the extra cost for the ease of building, if nothing else.

Also the 750 appears (to me), to be a more substantial and useful aircraft. The 750 can use a number of different powerplants including an 0-200. If one is on a tight budget that fact alone could help the 'scrounge' factor on the project.

Another route might be to purchase a 701 that is already built. Since the 750 model was introduced a lot of builder/owners are 'moving up' to the 750 and selling their 701s.

Another LS aircraft that has my attention are the SkyRaider
kits out of Idaho. (I'm sure you know this). Both models are interesting, and while I would prefer the 'Frontier' model, the 'Super' is pretty interesting, too.

Good luck on your search.
