There are also many options at the low power end depending on whether you want 2" eyepieces and what apparent field you are after.
Note too 1.8x Barlows were available some time ago but they are not that common now and even. Tele Vue have dropped the 1.8x and 2.5x Barlows from their line-up in favour of 2x and 3x Barlows. (2.5x available as Powermate).

Points Taken.
I chose magnifications just for example. What eyepieces and magnifications visual astronomers use is really upto them to make the judgements based on the optics etc. as for Barlows I do not use them as my imaging does not include planetary stuff.
