I'd worry a bit about the clubs fitting and the lie angle and such.
Anyway, it looks like you know to check out a sellers feedback before buying, here are a couple other ideas as far as eBay buying in general goes:
If you have a question about an item, go to another of the seller's listings and ask the question from there. This will add a bit of work for the seller, if they want to add your question and their answer to the item description page. Maybe other interested buyers will not bother to ask a question, instead just continuing to look for a similar item that already has the question answered in the item description.
If you see an item that you want listed in either auction or "Buy It Now" format, send the seller a message asking if they will accept $x to and the listing and sell to you now. some sellers are impatient so telling them that they'd not have to wait for the listing to end, you'd send the money right away as soon as they accepted. All they can do is say no, and you could still bid or "Buy It Now" anyway.
If it's an auction and they say no, and you want to bid, use a sniping service such as Bidball.com to bid for you. It’ll bid in the last few seconds, helping to save you $ and avoid shill bidding.
If there is a particular item that you want that is relatively rare on eBay or goes fast when one is listed, use ebuyersedge.com to set up a saved eBay search for it. You’d get an e-mail whenever a match is listed. You can use the price, category, exclude word, etc. filters to filter out nonrelevant results that you'd get in the e-mails. Excellent for “Buy It Now”s priced right.
A bit of a longshot, but if the item that you’re looking for is difficult to spell, try a misspelling search site like Typojoe.com to find some deals with items that have main keywords misspelled in the title. Other interested buyers may never see them.
