I bought a cheap ebay antenna a couple years ago which got me the red and yellow channels on the tvfool chart but pbs didnt come in solid.

The reason that PBS (WENH, channel 11) did not come in reliably was because the antenna you were using had minimal support for VHF frequencies (channels 2-13).
Were you able to pick up WUNI (ch 27.1, RF 29) with your old antenna?
With a very good antenna, amp, and rotator setup, you can usually expect to pick up channels with a Noise Margin down to about -5 to -10 dB, but it looks like WUNI and WUTF are Hispanic channels, and I don't know if you care to receive them or not. If you do not need those channels, then the weakest non-Hispanic channel on your list is WPXG (ION, ch 21.1, RF 33) with a Noise Margin of 10.4 dB, which can be picked up with a lesser antenna.
If the first four stations on your list are good enough for you, then I'd recommend something like a Winegard HD7696P antenna and a Channel Master 9521A antenna rotator. If you want to split this signal to multiple rooms or if you think the cable run from the antenna to your TV is going to be very long (more than 60 feet), then you can add a pre-amp (Winegard AP-8700 or Antennacraft 10G202) to overcome the splitter/cable losses.
If you also want to get channels down to about WUTF, then you'll need a larger antenna like the Winegard HD7698P, a Channel Master 9521A antenna rotator, and a pre-amp. In this case, the pre-amp is not optional because you will need it to preserve as much signal integrity as possible coming out of your antenna.
Just FYI, your old antenna appears to be "cheap" with exaggerated marketing claims (125 miles is pretty far-fetched). Similar antennas have been known to have poor construction (rotator motors that die after 1 year) and inferior design (poor antenna sensitivity and mediocre amp specs). The price may be attractive, but the quality is really lacking.
If you buy anything that includes an amp, be sure to look for the Noise Figure spec on the amp. A "good" amp should have a Noise Figure that is 3.0 dB or less. Some "cheap" amps won't publish their Noise Figure spec, and that's usually a sign that it's performance is not very good.
The antenna gain (that is, the raw intrinsic gain of the antenna, not counting any amps) and pre-amp Noise Figure are usually the two most important factors that determine how well your system can pick up the weaker stations. You want to have the antenna gain as high as possible and the amp Noise Figure to be as low as possible.
