depending on AM or LT I'd guess round about £250-280. I'm basing this on the fact that a new etek4 is £380 and they'll go 2nd hand for around £300. rough estimates tbh, but if you want an accurate price, just search in the for sale section for etek3 and see what people are listing/offering for themNeed pricing advice for a used Etek 3 in good condition
