I use the Guarder 6.02 and it's alright for what it is. Nothing amazing like Prommy or PDI but it's still an upgrade and pretty cost effective too compared to ~$100 Prommy barrels.

Remember bore consistency and trueness are more important than having the tightest bore possible (typically 6.01). Plus the tighter the bore the more you have to clean it out to prevent dust and dirt from jamming BB's down the barrel. (I clean my 6.02 out once every few months and can report no detrimental performance with that cleaning regimen buy YMMV depending on playing conditions/environment and such).
