I bought the same one about 2-3 years before that and it runs perfectly, only had it cleaned once and I wear it everyday. I don't think I'd cough up the coin for another at today's prices which are about 7-8 times more than I paid back in the day.
Here's the original receipt and that was a lot of money back then. No way would I fork out $7-8,000 for a new one; cost me $350 to have it cleaned...... If it ever quits running I may have to sell it......
