New NP:SEC lab advice

I'm getting ready to refresh my 2013 NP:R&S lab to prepare for NP:SEC. Need some advice on my plan.
Past NP:SEC seemed to point at 1 or 2x 5510s and 1x IPS appliance. I'm debating on buying a new 5506-X although that will blow a good chunk of my lab budget. I work on tons of ASAs at work but most of them are in production. Could someone provide some guidance on what contemporary NP:SEC lab topology would look like? At the moment, I am leaning towards 1x 5510, 1x 5506-X and no IPS appliance in concert with my NP:R&S lab (2x 1841, 2x 3560, 3x2950). On the software side, I understand I'll probably also need to run an ISE OVF but nothing else software-wise.

Cisco Adaptive Security Virtual Appliance (ASAv) - Products & Services - Cisco
I don't know if it's available as a demo at this point, but it's supposed to be added to VIRL soon.
Edit: Of course you can just use your CCO to download ASAv (unlicensed) and use VM Workstation to lab up versus all the cludge of VIRL.
Throw in other firewalls and get crazy!!
I'll be graduating in a couple of months and after I do I plan on beginning work on updating all of my CCNA level certs to CCNP. I used GNS3 for my CCNA-Sec but found as most do that touching the physical gear seems to make the process better. Here's what I've got to go towards my CCNP-RS and CCNP-Sec studies:
4 - 1841 (384MB-D/64MB-F)
2 - 2821 (1GB-D/256MB-F)
1 - 871 (?/?)
1 - 871 Wireless (?/?)
2 - 2960 24pt
2 - 3750 24pt PoE
2 - ASA 5520
1 - ASA 5505
1 - 4260 IPS
The two 871's and the 5505 were given to me, and while they aren't incredibly useful, the wireless function is nice to have so I can roam to a different room when my legs go numb from sitting down for hours on end. I may need to add a couple more switches and might do another 4240 or 4260 for one of the "branch" office configurations, but I'm hoping this will suffice for the changes made in the CCNP certs I'm after.
Also I have two servers running 2012 R2 that I use as Hyper-V hosts, I can get about 6 VMs on each box to give the network configs actual traffic to work with.
Any thoughts/ideas/criticism?
[EDIT] Scratch that thought...it requires a service contract, though I have no idea what [device the contract would be] for.
[EDIT] Found something called ASA-1000V which doesn't require a service contract. It only goes up to ASA OS 8.7.1, whereas the ASAv goes up to ASA OS 9.4.1.
