Hi Shakespeare,
Are you saying you want to volunteer to provide us the USA prices in US$/HP per each rack? That would be lovely, thank you very much in advance ;-)
Kind regards, Garfield ;-)

LOL, OK!
Pittsburgh 420: $899 USD, $2.14/hp.
Pittsburgh 270: $649 USD, $2.40/hp.
Pittsburgh 360: $899 USD, $2.50/hp (but also portable, with a locking lid).
Definitely the LC9 0r Mantis are lower cost options, if cost is the OP's primary consideration.
