JTAG multiple devices

Greetings,
I am new to JTAG and and I am working on a project that that has an
Atmel AVR. I want to be able to use JTAG but have not bought any
programming/debugging devices yet. I would like to get something that
is compatible with other products that I see myself using in the
future such as FPGAs or other microcontroller families. I am on a
tight budget and I want to get something that will work with multiple
devices.

Additionally, if all the chips that I use adhere to the IEEE
standard, one JTAG device should do, right? I may be missing a major
point and do not understand why is there a plethora of JTAG devices
that are specific to a certain hardware or software.

Any help is greatly appreciated.

Thank you,

--A
