That's a pretty good price for a scorpion, I'd say charge it. The only drawback might be that if you ever need it serviced you'll have to send it back to Japan. I know I've got a calcutta 200XT that I sent to Shimano for some reason about a year ago and they couldn't do anything because they don't have the schematics for it. So, you've got the curado SF which seems to be slightly lower than the scorpion, but is more readily available in the US and can be serviced in the US while the scorpoin seems to be a bit better reel, but not as easily serviced. I'd go scorpion.
