TransTints Dyes - The Voice of Experience?

Technically, this isn't a question of skinning a teardrop. But since most conversations about protecting and coloring wood seem to happen in this forum, I thought it would be more appropriate. Moderators, feel free to redirect me.
Back story: I'm tired of using generic pigmented stains. The only hardwoods that seem to stain well are oak and ash. Everything else - birch, alder, maple, poplar, aspen, cherry, and all the softwoods like fir, spruce and pine - don't want to take stain well. I'm tired of dealing with the blotching, and I refuse to restrict my designs to the tried n' true varnished raw Baltic Birch :p
I've spent the last 48 hours of my life crash-coursing in hardwood finishing. I'll spare you the gory details. Long story short, I'm interested in TransTints. They are dyes, not stains, intended for interior use. They are soluble in just about any water- or solvent-based finish (not oil-based), and can be used as "stains" on bare wood or seal coat toners. Colors can be mixed to achieve custom colors. They are somewhat similar to aniline dyes, but they have better color retention and versatility.
I'm thinking of making the jump to dyes and forgetting about stains entirely. Only so much room in the shop, after all. But at $20 for a 2-oz bottle, I'd like to hear from any voices of experience before I shell out $150+ for a set of dyes and learn a new skill.
Fire away.
