RG350 or RG350P for 8-bit gaming

I'd like to get a handheld emulator for playing 8-bit games (mainly SMS but also ZX Spectrum). The RG351P was recommended to me because I'm not very technical and it seems to come preloaded with everything needed for it to work straight out of the box, without the need to install firmware, emulators or even games.

I've looked into it and the RG350 actually looks more appealing to me because it's more affordable, includes an HDMI out and possibly has a screen resolution more appropriate for gaming in a 4:3 aspect ratio. However, I get the impression it requires much more set-up than the RG351P.

Can anyone who has experience with both machines give me any advice here, please? Will the RG350 allow me to play all my favourite Sega Master System games straight out of the box or is it more convenient to get the RG351P, despite the extra cost and lack of HDMI out?

 

From what I can tell, the 350 comes with a Megadrive/Genesis emulator that will run Master System games. Think I'm going to go with the 350, rather than the 350P as cost is a factor and it's quite a bit cheaper, particularly as it's on sale right now. I may want to fiddle with the firmware to get the HDMI port working but will cross that bridge when I come to it.
