Buy the Wei-ya chassis from Alva (826H) and the matching yoke from them and do  a yoke swap and reconverge.  The chassis is about $55 and the yoke is about $20 and shipping is about $10... all told ($85), less than the $95+$12 shipping for the Jennshinn 8liners chassis.  However involves more work to swap out the yoke, realign, reconverge, etc...
