They are great switches and I highly recommend them in general (I have about 10 across sites for work, bought new and from eBay) it is just they are not quiet. For 14 PoE ports you are going to need something with fans anyway so I would say pick one up on eBay and see how it works out for you, if it is too loud you can turn it around and try sometime else.
The last ex3300-48P I picked up I want to say was ~750 but I was patient and trolling eBay for quite a while with search on ex330's < 1k to pick them up.
If you have enough space for 2U of equipment, you may be able to find a 16 port PoE switch / power injector that is more silent, but I don't have experience with any offhand.
The HP, Juniper, and Cisco PoE switches I have used are all on par in terms of noise.
