The sig gen in the last link would do, you don't need an FM generator or sweep facilities at this stage in your radio career, there's possibly at least one niggle I can see, It looks as though the output attenuator might be and adjustable preset if so then that might be a bit of a pain.
My recommendation would be an old style second hand job that's known to be working, the ones I have owned and used over the years both in and out of trade were the Advance E2, an excellent generator for servicing radios, does not cover the full VHF/FM band but to be honest that facility would rarely be needed as most FM tweeks at VHF can be done using on air transmissions.
The others I've owned/used were mainly Avo's, those being the Avo All Wave, the Avo Wide Range (aka the MK1) and the Avo CT378a, all excellent generators but bear in mind that the CT378a, excellent though it is, only goes down to 2Mhz.
Also had a Marconi TF144G, bit of a lump but a very good generator but the weak point is the thermocouple for the output meter, more often than not it's shot and not obtainable, the one in mine was ok.
All the above except the Avo CT378a will do all the common IF frequencies including FM IF frequencies, all the above have built in internal modulation facilities and both stepped and variable attenuators.
The most popular trade sig gen back in my day was the Advance E2.
