I have a Poli (Pigeon Gun - 32" barrels, Brileys) and three RBL's.
The Poli is a substantially better gun in terms of fit and finish. It cost roughly 50% more than the RBL's and is worth every penny of it.
It also has a certain dynamism in its movements (even with 32" barrels) that is more noticable than in the RBL's.
Having said that , the RBLs are built for stout and will probably last several lifetimes (as will the Poli) and are a terrific bargin in a side x side.
