exactly ...
what is "affordable"?? what is your price range?
"kits" come in 3 flavors
Traditions types - never built one, but I hear you can slap one together in a weekend. - someone else will chime in.
Kibler - never built one, but have the top rating all around will cost you around $2k after exchange, shipping and duty. depending on the stock grade.
everyone else. will cost you about $1100CDN to get all the parts up here (if you can find them) - but these are unfinished parts that need a LOT of work, rough castings, questionable inlet jobs, tap, drill all holes, metal and wood finishing.
