Im afraid that you will be greatly disappointed with those 2 machines. For PB use they are way to small...and I would imagine the quality isn't all that great either.
If your serious about making a decent investment I would shop around a little more. machine tools are alot like everything else in that you get what you pay for.
For a mill I would consider this
G0463 Mill / Drill
It is the same as the Sieg X2 only sold through Grizzly...this is about the smallest I would consider for PB use. Ive been able to handle that machine there at Grizzlys showroom and was very surprised by the fit, finish and size.
For a lathe I wouldnt go smaller than this
G4000 9" x 19" Bench Lathe
Its your standard 9" X 19" and should accommodate most PB related machining that the average hobby customizer will face. However the next step up in the grizzly line would be an even better choice considering the 1" spindle bore, anything smaller becomes a challenge with any barrel work you may want to do.
Those are just few options in the "moderate" price range. If you dont have the coin to drop on both machines....just wait it out and buy them separatly. It'll be better off for you in the long run...trust me.
