newer mossbergs are actually very well made for its price and i am sure Flanigan has one that looks like mossy with tons of aftermarket parts for it.
I also collect beretta and do have A400 Xcel and have tested sx3.
I have purchased Xcel instead of SX3 becase it just felt better. shell feed, ejectors, recoil, balancing of the stock was just much better for my taste. I am sure there are people that are totally opposite then i am tho.
red or blue = they are both ugly and i had to buy one since it was the ugliest beretta ever made. Well UGB25 is uglier and i do have that too.
If you like to try something new and dont mind spending few $$ for your gun needs, just order whatever you want to play with and see how you like.
once you pull the trigger, it is a used gun so if someone that has a gun that is in very good condition with right price, i would but it in heart beat. specially if its beretta since i just love them lol.
However i have seen some dealers that sell the sx3 Exhibition for $1300 or less.
try gun dealer or dawson creek sporting if they can track one down.
