[s-cars] Modified Air/Fuel Meters- worth it?

[TM]

I saw this page from Rennlist and was wondering if anyone
has used something similar and if it is worth it. Sounds like
it, but I'm wondering if I can get it done for less money locally.

I already have the gauge so it wouldn't be a big deal to ship it
to these guys for modification, but if it's a really simple mod,
I'd rather have it done locally.
