PC Peripherals Which JTAG downloader for a learner

[nimod]

Hello Friends,

I wish to try my hands on JTAG.
(That sulemani kidaa, you know)

To start with jtag, which make/model of jtag will you suggest?

My experiments will be limited to some old modems/routers and mobile handsets.

I found a cheapo one:
