Choosing the right JTAG (advice needed)

Hi,

I was looking for an 'multi-purpose' jtag connector,
I wish to use it in many situation (not only to flash the pm3 !)

here is some product I find on ebay, could you tell me, which one is the good one for hacking

by preferred order :

1) J-Link V8 USB ARM JTAG

maybe a segger clone, with a lot of features.

2) Blackcat-USB-SPI-JTAG

the last version of blackcat

3) altera-Mini-Usb-Blaster

USB blaster, fear !!

4) Serial-Port-DB9-9Pin-Male-to-JTAG

the cheapest!, with DB9 COM connection

feel free to point me other jtag device, if they are better/cheaper.

Thank you

Re: Choosing the right JTAG (advice needed)

1) Bought: it works, it includes cables, flashing software and it is multi-purpose; to avoid clone-related problems have a deep read here [software is also downlaodable here] - my experience here. I think this is the most featured&cheapest

2) I own it since a long time but it seems not to support jtag, only ejtag (more info/tests here); support service never answered my questions about that subject

3) Never heard of; reading description it seems not to contain the needed flashing software !

4) Serial port is obsolete and also description seems not to include software.
