I've got a LH 870 express that's 20yrs old. Decent enough only complaint would be lack of model options beyond 28' 12g options. Nice enough at 300 ish for an express but nuts at 750. The BPSs are nice and well finished but heavy. Fine for waterfowl but lighter is better on long upland hunts.
$750 puts you in spitting distance of some nice semi options, benelli montefeltro, franchi affinity, used Rem 1100s and 1187s.
Find an older LH 870 wingmaster, much better fit finish and slicker than snot when broken in
