Planetary Eyepieces

Would like to ask the group their opinions on better to best planetary
eyepieces for relatively fast refractors.
Just purchased a Williams Optics, 105 ED triplet APO (f/7 FR at 735mm
FL) and am pleased with the views of Saturn so far using my two Meade
eyepieces (an UltraWide, Series 4000, 8.8mm,, and another 4000 Series,
12.4mm Plossl), on top of an Orion 'Shorty-Plus' barlow.
In my box is a 3mm TeleVue Radian that i've used a couple of times. The
Radian, however, is pushing the mag past this scope's capacity and the
image quality breaks up at 245X. Maybe if atmospheric conditions are at
good to excellent I can push it to 245X, but not lately.
Question is this: has anyone had experiences with the Burgess Optical
60° planetary eyepieces (supposedly designed by TMB) that I'm seeing
advertised for $99us ?
Been thinking about their 4 or 5mm to get somewhere in between the 167X
and 245X that I have.
Any thoughts/comments?

Thanks in advance.
