Affordable 300b Replacements

The time has finally come to replace the stock Shuguang 300b-98s on my Triode Corp. trv-a300se and I'm hoping to get some suggestions for affordable (<$300/pr.) replacements. I listen to all styles of music but particularly modern electronica, rock and alternative. Any suggestions on what might work well with these types of music? I've been looking at the usual suspects--EH gold grids, JJs, Psvane hifi series, Shuguang 300b mesh plate, or Gold Lions (tho a bit over budget)--but with no way to demo. Thanks to all for your help.
