Funny I should see this on the front page, since I’m one of the (likely) few lunatics on HN who rents a pier at Starfront. So far I can say that they’re definitely one of the better offerings when it comes to remote observatories. Shipping my gear and setting it up was a tad painful, but once everything is operational the rest is a breeze. Plus the onsite staff are very responsive when it comes to servicing my CDK (cleaning/upgrades/resets/etc.)
For those who want to try telescope colocation on a budget, they also have a relatively cheap ZWO Seestar pier option. I haven’t given _that_ a try yet, but I’ve heard good things about it on Cloudynights.
