When it comes to phono pre-amps ('phono stages', same thing just a different name), you'll be presented with a bewildering choice ranging from under £20 on Ebay through to £1000 for esoteric Hi-Fi versions, but most of your attention will be focussed on the question of whether the £20 versions are good enough or if you should spend a bit more.
The cheap ones under £35 are suitable for home DJs. They're a bit noisier than the Hi-Fi versions.
Without blowing mad money, Pro-Ject's Phonobox MM at £60 is where you should be starting to look for Hi-Fi use. This will be as good as anything else you can buy up to £130.
Now, the next thing you're probably thinking is "£150 for a TT + £60 for the pre-amp = £210.....Is this my only option? " The answer to that is no. You can get the next higher model in the Pro-Ject range which has the same quality as the £60 pre-amp built-in, and it will cost you £190. Look for the Pro-Ject Elemental. You also get a USB output. This means you have the option to rip vinyl to a PC or MAC. As a standalone box, you'd need to spend £100 to get that. That makes the Elemental at £190 worth £250 if you had to buy the bits separately.
The other option open to you is a s/h phono pre-amp. Search Ebay for the Pro-Ject pre-amps, but also look at NAD and REGA. Both are very highly respected Hi-Fi brands. You can't really go wrong with them.
