i'm a carpenter & already had a framing gun, 2 trim guns, a brad gun, & a staple gun. all are Sencos. my original reason for buying senco was that they have a luggage type latch that opens the nose for clearing jammed nails. most others require disassembly. all guns sooner or later will jam now & again. i find my guns have fewer problems when i buy senco brand nails instead og generic nails. also an oil type compressor will outlive the oil-less types like the porter cable units sold on the big box stores. BUT if all you are using it for is to build hives an oil-less compressor should last a long time. my compressor is used almost daily.
For frames;A small pneumatic nail & staple gun with a 125 psi compressor has worked for me over the last 3 years. I use 1.5 inch staples.Supers;Nails, hammer, & wood glue. Screws are fine but a box joint is already strong. The nails just keep it in place.
