Im buying my partner a fishing reel for xmas and I need help!?

I need to buy a reel for my partner but havent got a clue what to buy?? It wud just be for basic fishing? Beginners fishing? Trout? Coarse? Not sea fishing though. Also I only wanted to pay about 30quid at the most. Would buying second hand be recommended off Ebay maybe? Please help by maybe suggesting a make of reel. Thanks very much!
