For anything like that I normally look on Amazon first. It is almost as cheap as eBay plus you get the reviews to help guide your purchase. Just go for something in your price range that has mainly 4/5 star reviews.
FWIW I would recommend the telescopic screw-in type. They are very stable and any damage the screws cause can be easily repaired with a bit of filler and paint if you need to remove it. Plus as you have it set up all the time it is great for "greasing the groove".
