Well, we've hi-jacked his thread...
I agree with you and I never wanted a 73 TX. I lost one of the green 70 models on Ebay a few years back when I stopped at $1,850. I kick myself for not putting $5,000 on it. I looked for 3 years afterwards to find a nice example of the green 70 or a really nice Gold/White 71 - drum brake - kick only model. After seeing them go into the 6-8,000 range, this little 73 with 5,000 miles came along for $600 delivered (it's owner found me hearing I wanted an old Yamaha).
This looked bad, but I knew it had potential - so, I'm the happy owner of a cheap 5,000 mile TX650.
