Spanky,
To answer your question seriously, you can get the 36lb Pioneer package for under $500 if you shop around. Whether or not this is worth it to you is how much you value the benefits it will offer to you. For me it was worth it. In an ideal world you could try one out before buying, but that depends on if you know anyone that has one - I haven't seen them for rent anywhere near me, but you could have that option in your area. Extreme Exposure has a policy of a full refund for 30 days for any gear you buy, try, and don't like - they're more expensive than other sources, but there is the peace of mind that if you decide you don't like it, you can get a refund.
bengalsmgtsucks raised the issue of weight integration - you didn't ask about this in your original post, but it is available as an accessory, in two different sizes (ACB and ACB+, 30 and 20lbs total respectively). Figure to add another $112 to $160 (roughly) if you go down this path.
bengalsmgtsucks is also a dive shop owner - you might want to send him a private message to ask if he stocks Halcyon gear, and if he can organise a sale for you. There are of course alternatives to the Halcyon brand, often each manufacturer has their own following.
And don't worry about the SS backplate failing if you buy a FredT backplate (which is an alternative to the Halcyon backplate if you decide to put your own rig together - not all all difficult) - there's about as much chance of it failing as a brick failing.
cheers
Ben
