There isn't a huge selection in that size range and it also depends on how deep your pockets are. Mono or cat?
Personally I'd always lusted after a Noelex but they were out of my price range. There's also the Macgregors if you must (but they do have more space than just about anything and are light to tow). The Farr 7500 is supposed to be and excellent performer.
