Half speed masters. Are they worth the extra scratch?


I just purchased a Dire Straits Brothers in Arms half speed master. I'm using a Pioneer PL530 TT. Can this album be played successfully on my TT? I put it on 45 rpm but there is no way to tell if it is spinning at the right speed. The speed control is working but not keeping a steady reading like when I play a normal 33 record. It sounds good but I'm wondering if they should be played on a different table. Also is it worth it to pay extra money for these? I payed 50$ for this album. Thanks for any information.

Like any other absolute question, it depends.

The tech makes me think of original R2R prerecordeds. They are fetching big $$ and they are crap.
Manufactured at double speed or worse.
That was funny MC, but... In general half speed masters do sound better, but I only have 33 rpm versions, no 45's. One 1/2 speed of Blondie Parallel Lines sounds worse the original Chrysalis version. MC would tell you to buy a $500 selected "white hot stamper" from Better Records. Not all of us can afford that unfortunately.
It's a 2 disc set done at Abbey Road with letter of certification. I will try the paper disc. I have it on 45 but the strobe I guess is only correct playing a 45. Maybe it's timeing is off a little for 45 rpm as it still moves a little at maximum set point. Spot on for 33/1/3. What cart is best for these records? 
Perhaps there is a problem with the turntable.  If that is the case, I wouldn’t buy expensive records to play on it.   A newer turntable may be a better bet in the long run.  
No, the TT has been checked out by the tech. He says it's in perfect condition. I just notice when set at 45rpm the strobe moves slightly. Does not hold steady like when on 33.
