You could get a refurbished time capsule they are cheaper. There are plenty of great routers on the market right now, but if you want time machine support its best to go with an apple router.
I don't really want a previous generation TC. I can easily upgrade the HDD in my old TC myself, and I'd rather spend the money on something that finally supports all the AC grade devices that we now have in the house.
The two routers recommended here, the r7000 and AC68u, both look great. I do notice however that Amazon lists them both as dating from 2013/14. So it seems they are of the same vintage as the current Airport Time Capsule. Hopefully some wave 2 AC routers will start getting cheaper soon.
EDIT: Macrumors is now reporting that Apple is withdrawing Airport gear from their stores. They're either updating the range or dropping it entirely...

Here's my wishlist:
- SSD drive cache to make Time Machine backups go faster. 4GB or 8GB, either one, I don't mind. 8GB of SSD costs pennies nowadays. Just get that backup done, get off my wifi, then transfer it to the multi-TB drive later. Apple has the Fusion tech to make it happen.
- iCloud caching. I want my photos and stuff available to my local mac stuff. I don't want to wait for my photos or videos to download before looking through them. (Apple will probably never implement this)
- iOS backups. The current system of only letting iOS backup to a local Mac is crazy now that many home Macs only have 128GB SSDS, sometimes 256GB. That's laughable considering that iPhones and iPads now have up to 256GB storage. How do I back up a 256GB iPad to a 128GB Macbook Air? I'm currently using an external HDD which is crazy considering that sitting 2 feet away from me is a Time Capsule with a vast HDD in it sitting unused and ready for action.
- USB 3 ports. I back up my Time Capsule to (another) external HDD. At USB2 speeds, a multi-TB HDD can take several days to back up which is crazy. There was a rumour that USB3 was left off because it can interfere with AC wifi. However, that seems a solved problem, given the flood of AC routers with USB3 ports.
- Wave 2 802.11ac, with active antennae to boost upstream reception from mobile clients with poor transmit power. This will really help out with FaceTime and other live video upload clients (Skype etc). Wave 2 also has MU-MIMO which helps with multiple high-bandwidth users (eg multiple Netflix streams). Wave 2 routers started coming out last year so it's time for Apple to incorporate this.
- Maybe incorporate Apple TV into the new Time Capsule? All the gubbins are there, it shouldn't take much extra.
Hell, probably none of this will happen. Apple may even be discontinuing the Time Capsule - it seems dead nowadays. Clearly more profitable for Apple to
ask tell us all to back up Time Machine to iCloud and charge us monthly for the privilege.
