Yeah, given the outdated appearance of the initial seekers and the insane prices they command, replacing them seems like a no-brainer. I have deemed the TRU versions "good enough", but MT definitely did a good job with those.
I have completely lost the urge to add to the MP collection. After completing XTB Menasor last year, I haven't felt the need. The only MP I've bought this year is a KO MP44. I like it, but not enough to replace the Magic Square version in my main display. 44 just went in the "Primes of all sizes" display with MP01, MP10, knocked up MP10, knocked-down MP10, Faith Leader, Revo v2, etc...
I have XTB's Springer on PO, but it feels like that figure is never coming out.
