First the bike; this bike seems to be good; not familar with the brand though thus don't have a good price gauge for you and Sheldon Brown site didn't have that brand listed; so maybe someone else might have a better clue then I.

There's no mention of the type of tubeset it is, though he does say that it weighs around the 20lb range which was very light for bikes in the 70's thus it must be a decent tubeset. Suntour Cyclone components was extremily good stuff and sought after today, however I don't believe they were the original components, the original may have been Galli but those didn't function well so the owner switched them out for stuff that was known to work superbly. 3T stems and bars were amoung the lightest you could get back in those days. The Maillard hubs were also very good and still sought after today.

The ad says that the paint and chrome are pristine and that's good. If you can actually see the bike then I would, then decide if you want it. But on the surface it seems like an interesting bike that could be worth $250...but make an offer of $200 and hope he bites.

E-Bay if you've been around it for awhile then you probably already know the tricks. First you need to make sure the person your doing business with has extensive history and most buyers have had a good experience and those that didn't got the problem resolved in a timely manner. One way to test the water is to ask the seller a question about the item and see if they respond, if not then forget it because more then likely their customer service will be poor.

Also don't bid on an item until the last 30 seconds of bidding is left if your on slow modem or 15 seconds on highspeed internet, then have a high limit your willing to pay and bid that limit and no more-don't get trapped in a bidding war you'll end up paying more then you wanted, but waiting untill the last 30 seconds will help prevent that. By waiting for the last few seconds anyone who wants the item will be scrambling to try to out bid you before time runs out and will fail. Also bid odd amounts not even like $21 not $20. For example an item you want has a current bid of $100 and your willing to spend $150 for it, so you wait for the last 30 seconds and then enter your bid of $151. Couple of things could happen, either the next higher bidder bidded $125 (this is an example of an even bid 5's, 10's, 20's, 50's, 100's, etc are even bid's) and you'll get the item for $126 (automatic odd bid because your limit was $151 and the automatic bidding only jumps $1 increments and you win on the odd bid as most people do but they don't bid that way), or someone also set a limit of $150 but you got it because you had the odd bid. I hope that made sense.
