Fiberstore switches; anyone have a review?

I'm comparing these three network designs:

1) 3 stacks of Aruba 3810s, 18 switches total, $225k.

2) 4x Aruba 5412R. $168k.

3) 20x fiberstore 35252, 2x fiberstore 29123. $26k.

I can't find any technical reason to not select option 3.

Have any of you purchased/worked with a FS.com switch yet? I've used their optics on a dozen or more projects and never had a problem.

It's just crazy to me to think that I'm contemplating building a network with 960x 1G ports, 4x10G uplinks from each switch, at a cost of less than $28 per port.

If you have better ideas, i'm all ears.

Actual requirements:

IDC1: 160 ports. IDC2: 460 ports. IDC3: 240 ports. All access ports must be 1GBase-T with PoE+. 802.1x authentication. VLANs. Routing is not required. There are existing routers. 

So, I know the question of "what should I buy" is not appropriate for this subreddit; I'm not asking that question;

I'm asking for a comparison of Fiberstore.com switching vs HPE/Aruba switching. Have any of you bought/worked with a FS.com switch?
