I only buy used weller equipment on eBay. I have a good collection of WD series, the WP80 iron is to die for. Generic tips can be had for cheap. I switched from Hakko a long time ago. Some people will argue that metcal is better but this is because of the power source and tip, metcal is the tip type that heats to a curie point and cannot be adjusted, not practical for home use, but great for production.
Look at a used Weller WD station on eBay + a WP80 iron, you won't be dissapointed. Don't be worried to buy separately.
IMHO the advantage with the weller WD + WP is how small the iron is. You don't have this large, unwieldy sledgehammer of an iron you get with the hakko's, it makes you a better solder-er by default ;-)
Keep in mind that this may be out of your price range if you are looking at the disposable type stuff from china, but if you don't mind buying a great tool in used condition, I really don't think you can go wrong with a weller WD.
