Dont rule out the dynamics - Shure sm57, Shure sm7B. Michael Jackson recorded the vocals for thriller on a '57.
The sm57 is also a general go-to for mic'ing up electric guitar amps. I've got 2 - however I dont really find a use for them on vocals (I have them mostly for live use and amps). But they can be dependable when on a budget and can come at a great price (think I paid £60 each for mine 2nd hand)
Shure KSM27 is another budget one that Ronan Chris Murphy raves about...
http://www.oktavamod.com/ - a company that sells modified mic's. The idea being to take very cheap mic's and 'mod' them to get them close to classic Neumann mics. I got the 'Ultimate SDC Mod' from them a short while ago. Sounds better than any other acoustic guitar mics I have...
They sell modded LDC's starting at about $350 (thats about £200?) and they have lots of info on what they do to each mic and shootouts (against U87's, U67's etc)
Golden Age Project R1 Mk3 Active - I think it is just within your budget. They have other mic's but this is the only one I have tried - It's pretty much the only mic we use for all female vocals. very thick sound (kind of the opposite of the rode nt1-a), very detailed and great for voices that are naturally bright/a little thin
Rode make a lot of mics. NT1-A is a very popular, good all round mic. I found that as my recording skills got a little better I got more and more annoyed by the brightness of the NT1-A. It's bright to the point of being harsh. I still use it for male backing vocals. Although, if I had other options perhaps not...it is a gooood all round mic though and will give decent results on whatever you put it on.... When I have enough money I'll probably send it to oktavamod to get it upgraded.
The SE mic you've looked at I have no experience with. These mics are generally like the NT1-A. Dependable, well made, perhaps a little too harsh....the same goes for the audio technica
AT2020. Thats another popular budget one.
Ones I would steer clear of are Behringer C1, Samson C1 (might be called something else but I think it is C something. The Behringer and Samson are the same mic, from the same chinese factory, with different badges
). AKG perception is not thought of very well either....
I had a Rode M3, which I thought was rubbish...and earlier versions of the Golden Age Project microphone I mentioned (apparently Mk1 and Mk2 were rubbish, aswell as the non-active version).
