870 Price check

I can buy an ANIB 870, 18.5" w/ factory extension, bead front sight, the new style (?) forearm and stock, and the "J" safety. It's missing the swivel attachment on the lower part of the barrel clamp, otherwise looks fine and function seems normal. Price 229.00 OTD, Deal or no Deal? After I get a few thousand rounds through it I plan on a Vang Comp big safety, Speedfeed buttstock and forearm set, ghost sights, and a light. Any problems changing the safety? Thanks for your input.
