Here'a link I found, as I am in your boat, but witheth oars in the water: I bought the kit, and am weaiting for a clear building table to start it!
Yes, I have heard the same thing. There is also a mentioniof teh Miniplane in teh Higlye book 'Bipes' and he does touch on its construciton, which is a nice help!
As for pricing,
www.sigmfg.com is a good place to start, as
this is Sig's page!
Then look at tower hobbies, and a few of the other 'online' ordering shops. Go to
www.greathobbies.com as well. They are canadian (with a US branch..) and you might get a better deal, with the exchange rate.. I paid about $140CAD for it, and this was just before Christmas..
They say this can be a ticky build, and that one shoudl really really take thier time with it..
