I'm with Panthers007 here. Although if you have no tools the cheap Cyclepro box is an ok start.
I pieced together my set, but i had access to shop prices and catalogs to compare stuff.
I bought my allen keys, 4-way and multi-micro screwdrivers at Sears, have SK open end/box wrenches, and two Snap-on adjustables. Other stuff is mostly Park. Notable exceptions are the Minoura truing stand/dish tool, Topeak workstand and a few odds and ends from Pedro's etc. I chose stuff to be the best product for the job made. Park while a little pricey has the best customer service and will always have my first look.
My portable kit is here:
and this all fits into a Park BK-1 with ease.
With this setup i can overhaul most bikes made in the last 10 years no problem.
