Cheap(ish) IEM Suggestions

[MaidenFan]

OK, so I'm a long-time fan of Sennheiser CX-300 IEM (in-ear-monitor) headphones, but I'm looking for alternatives, as my current pair have given up the ghost.

I'm tempted to stick with habit and just order another pair of CX-300s, but are there any others out there that are worth buying? I have used some Creative EP-630s that came with my (now lost) Zen X-Fi, and they were as good (if not slightly better) than the Sennheisers.

What I'm looking for is a noticeable difference, but at a maximum of £30 - I would love to go all-out on a pair of CX-870s but I just don't have the money (yet!).

I'll be ordering on Wednesday (don't want to be without my Zen for too long!) so any suggestions are welcome
