What should I buy? and which firmware should i use?

[Nexus13]

Hi there,

So I'm really green to all this and have spent the last 5 hours reading everything I could find about Map this, GMDL, etc etc. now its 1 am ugh.

couple questions i need some help with:

background: I have a phat psp with 3.71 m33 -4 on it with the 1.5 addon

1.) which firmware should I run Mapthis with?
is there any difference running it on 1.5 vs 3.71

2.) which is the best/preferred GPS unit to buy?

PSP-290 or a generic one?

I read that psp-290 isn't as good as those holux ones unless you attach an extension cable and even then its still not comparable. Is this true?

and what about audio. do you only get audio on the psp-290 or can you on some generic ones.

If generic is the way to go. which one to buy!! ahhhh!

thanks in advance for any/everyone's help.

I have the PSP-290 official running it on 4.00M33 and it works fine. Strong signal and quick response.
