The Synthetic Terrus looks bad on paper but handles & shoots well,it feels better than its wooden mate.It is longer & a bit heavier than a 99 the .22 barrel is a bit tight on the lead with some pellets.
The Century is a true bargain for those who want an eighty with out the work & i do like my 80's.
The LGV Ultra & Master Pro are superb,the LGV Master has the same 25mm internals with a plain stock but it works fine.
The Challenger same internals again but a synthetic stock fitted not my favourite but its a bit cheaper.
The Walther range weather Truly Walther or not get some stick but you will be hard pressed to find others that shoot as well from new with out a fettle.I would urge you to try one.
The LGV range are well made & finished better than the lower end Terrus range IMO.
