Personally, I don't think I'd pay $175 for anything that wasn't a proven morph.
I've seen some interesting stuff for under $50. At the show where we picked up our female, there was a snake that was being sold as a normal (I think around $30) that had a decidedly green tint to it. If it had been female, I probably would have bought it. While I've seen some pics online that looked greenish, you can never knnow how true the colors are showing up on your monitor. I have never before or since seen a BP in person that looked as green as that one did (or at least not as green of my memory of it is...lol)
I've also seen het pied males for $45 from someone who is not very well known, but the little info I could find on the BOI was all positive, and while there wasn't much, it did go back a few years.
Those are just the 2 that stand out the most, but I've seen others too.
BUT, the bottom line is: if you are happy with your purchase, then the price is ok.
