Orvis Spectrablend dubbing collections, good base for newbie?

Hi all,

I'm a new fly tier, looking to build up my dubbing collection. I'm
looking at getting Orvis' Spectrablend dubbing assortments -- one for
dry flies, one for nymphs, and one for caddis - which it seems would
cover the entire spectrum of what I might need, and in handy little
containers no less.

Any opinions? Is this what I want, as a good base collection of
dubbing materials?

[And to be clear: I'm not too worried about having a few colors that I
don't use. I've already had the frustrating experience of sitting down
to tie a fly and not having the proper dubbing color, and it's worth
$45 (3 assortment collections @ $15 per) to me to avoid this in the
future.]

Thanks for your thoughts...
