There are plenty in that range, but you will never get one that hasn't had someone moan about it, because some people seem to expect their £500 rifle to match the £2000 rifle it has a passing resemblance to.
Equally some manufacturers are hit & miss with quality control, Artemis seem to have that problem, people with good ones rave about them while others have no end of leaks, or other issues.
I'd always say buy a better rifle used than a cheap one new, AA S410, S510, BSA Scorpion or Ultra, Or pretty much any FX are all worth a look used.
Also worth making a shortlist & looking for youtube reviews to watch.
