OBDII protocol question

I am looking into picking up an inexpensive OBDII unit and I've gotten
information overload to a point that I am looking at too much conflicting
info...

I have a 2000 C70 Convertible, OBD II port.

what is the protocol I need to be sure the unit can decipher? I like a
cheap U380, 30 bucks, here is the info:
a.. SAE J1850 PWM
b.. SAE J1850 VPW
c.. ISO 9141-2
d.. ISO 14230 (KWP2000)
I 'thought' this car was ISO 9141 compliant... ??

Help!

it sounds like this refers to another thread. the unit sounds right.if
it is not return it. if purchased locally, that should take <5mins.

i'm not sure you need to buy a new unit. i used to steal time on my
mechanics. now, she is linked to my mainframe. the world changes, i
used to ride a Norton.

Thanks Richard... I didn't want to muddy the waters by going tooo off
topic... I was looking at a U380 unit,
down below... some also mention Actron's on ebay for $40.. I await their
reply back.. but this vendor advised, as you, that it should work...
