I saw a HP-48SX at flea market and I couldn't resist.

[HP67]

That sounds right from what I have read. I do not remember prices at the time they came out because my trusty 67 was still fine and I didn't want an LCD model and was not in the market for anything. The 41 had just come out when I bought my 67 and I had no interest in it although the guy in the store pushed it very hard.

I do not regret buying the 67 over the 41. I just regret not also buying the 41. But I did not have the money for both.

It is a mixed blessing your SX is in perfect cosmetic condition. That will make you less willing to butcher it. Although if you can convince Han he can probably fix it and return it in perfect condition.
