Hi,
Obviously, there is a large selection of pre-owned ("used") ones on places like Ebay. If you are keen to buy a new item, it may be worth trying this one at £149 (new):
Shop for Teac TN175 (Black) Turntable with Richer Sounds for expert advice and lowest prices guaranteed

It's not a big name "audiophile" brand, but I owned a slightly higher model TEAC turntable (£320) for several months and it was actually rather good. This one has an MDF chassis, a built in MM phono stage (so you can use this with your active Edifier speakers), and the option to upgrade the phono cartridge, which many cheaper decks will not allow. The reviews on RS seem quite positive also.
If you can find a cheap phono pre-amp somewhere, possibly used on Ebay, then you can get a refurbished Project Primary E from Peter Tyson for £159.
Please note, products are a B grade refurbsihed unit. The box may appear slightly tired but the unit is in full working order. Like when the original, now iconic, Debut turntable burst onto the scene in 1999, the Primary E has been designed to offer a hi-fi friendly alternative to vinyl music...

They also have some slightly higher spec Project turntables with built-in phono preamps for £210, if you budget can go a little higher.
Hope that helps. My advice would not be to go too cheap, nor to buy anything on Ebay that is very old or that seems "too good to be true", as this can potentially lead to disappointment and lost cash. I speak from experience.
Kind regards...
