B&M vs Transgo opinion and budget $$$

I like the Transgo kits. Some B & M kits omitted things like accumulator springs for really hard shifts. Sounds tough, but that can shock the trans components & break parts.
The T kits seem to have more thought...& more thoughtful....engineering in them.
I had the pleasure of speaking with the T founder, Gil Younger, before he passed. He complained that his company engineered the kits & others copied them....
