Sell the X heads and buy a set of Speedmasters. You could probably get the money to buy them by selling the X heads, unless you're just wanting to use them.
I was going to get speedmaster heads for black Friday, but my 4k national licensing exam had to be paid last semester. This semester I have 2k for my state license...
Speedmaster heads are about 1800 assembled right now... so more than the 11-1200 than they are on black friday.
