Yamaha DTXpress/DTXplorer/DTXtreme

For the last few years I have used an old bass amp (hey, I am on a low budget!) for my DTXPress kit.  Poor sound, but it got me by for practicing.  

I read about connecting up PC Speakers and heard that they would sound rubbish.  So for a laugh, I connected up my Logitech X-230 PC Speakers (twin speakers + sub) at a cost of �32.  I was literally blown away with the quality!  No distortion, crystal clear.  Not terribly loud, but way loud enough for my practicing.

So I thought about spending another �32 and getting another set from Amazon.  Before I do, has anyone else tried any other PC speakers for the �50 mark which do the job even nicer than my Logitechs ?

Thanks.
