I too have bought & sold quite a few things on ebay over the years ... and have definately run into some individuals that didn't take it upon themselves to provide the greatest customer service.
I think alot of people think of selling items on ebay as a yard sale rather than more of a business. I know when I sell something, I promise to ship within 2 days of receiving payment ... and I provide a shipment tracking number to my customers as well.
I have had to escalate issues to ebay and paypal, and they usually do a good job of handling the issue. The only other thing you can do is leave negative feedback & comments about that seller so that other people are warned.
I have never bought anything over a couple of hundred dollars off ebay though either ... if something is that expensive then I usually like to buy it from a reputable store (online or offline) that I know isn't going to be unreachable the next day.
Sounds like you got a pretty good deal on the clubs gulfsidebo, maybe waiting a while longer for them to be shipped is a small price to pay for getting such a great deal? :) In any event, be sure to report the seller & leave negative feedback for them!
