Does anyone have Sheridan Ultralux Medium Support Polyester Pillows?

MrB and I are sick of our Dunlopillo Latex Pillows and I would like to buy some new ones, but not latex or feather ones...
I saw these Sheridan Ultralux Medium Support Polyester Pillow (currently $30 at Myer), are they good? I know, I know, it is recommended that one try out a pillow in store before buying ... but  the thing is ... I don't think I will be able to get MrB to come along, and besides, I find the whole pillow testing in shops thing a bit awkward :(
What pillows are you currently using? Are you happy with them?
