Price is subjective. Quality should determine the price not just the weight. I would pay 100-120 for a very high quality well patterned cinnamon at 100gs. That's just me though because I also wouldn't buy a scaleless for 50.00 at breeding weight for a pair. Its all in what you want. I wouldn't buy a 40.00 cinnamon but that's just me.

FYI, I was at a big pet store in Pueblo Colorado last weekend and they were selling normals for $99.95 plus tax, so about $110. If you were selling at a show and you had the only one in the whole place and someone really wanted it you could probably get $120 for just about any single gene morph. Keep in mind that on Morphmarket you also have to pay shipping that can run up to and over $50. So $70 on Morphmarket = $120 with shipping (or so one could argue).
The breeder, not the price should be what you are looking for. Getting a healthy snake from an experienced breeder that specializes in that morph AND feeds according to what you want to feed (live or frozen) is worth its weight in gold.
