I generally love the quality of ProbeMaster.com probes, but they don't make those specs unless 300MHz is a typo. I've not seen any 1:1 probes that do higher bandwidth. 30MHz is around the limits I've seen, though I haven't looked that hard.
tggzzz:
What is "inaccurate" about your existing probes? Having a sharper tip probably won't improve accuracy.

At such frequencies there are many ways in which probes can be misused. For example, what is the load they have on the circuit? (Hint: not 10Mohm!) Will that affect your circuit?

Significant improvements in accuracy might require improved probing technique and/or a different class of probe. FRI see the references at https://entertaininghacks.wordpress.com/scope-probe-reference-material/

Sorry for not being more clear, I've noticed when comparing the waveforms that these probes see vs. a Tek probe on the same scope that these tend to have more noise. The finer tip is needed due to the size components I work with, 1.3mm in diameter on the H&S probes vs .75mm in diameter on the Tek probe I have.  I'll read the link, but I was trained on using scopes by two seasoned electronics engineers, so I'm confident I'm using them correctly; however anything is possible.
David Hess:
The Probemaster 4900 Oscilloscope Probe Deluxe Kit appears to have exactly what you are asking for, but 300 MHz means a x10 probe.
