Hi!
I've tried for 2 weeks to get my nRF24L01 working but it just doesn't want to. I've made sure that the module is connected to the correct pins multiple times now and I've tried a multitude of different codes but nothing is working. I suspect something is wrong with the hardware or how I've connected it but I'm just done with this transceiver. Are there any other cheap alternatives I could try instead?
The nRF24L01s do work, so if they dont work for you then you either have them wired or powered wrong or they are faulty.
As for alternatives, then that rather depends on what you want to use them for, application, speed, distance etc.
Did you try powering your nRF24Lo1 with two AA cells in series? Made my devices work.

If you read and, closely, follow Robin2's simple rf24 tutorial you should be able to get them working. That tutorial sure helped me. Run the CheckConnection.ino (look in reply #30) to verify wiring between the radio module and its processor (Arduino).
Make sure the rf24 power supply can provide enough current. I use homemade adapters like these. They are powered by 5V and have a 3.3V regulator on the board.
If using the high powered radios make sure to separate them by a few meters. The may not work too close together.
Reset the radios by cycling power to them after uploading new code. I have found that to help. They do not reset with the Arduino.
Yes, thank you, @Whandall. I saw that a couple of days ago and really should have remembered it.
Just add it to your template. 
1MB will work with the older NRF24L01 (without+) too.
I just did that. It is now imprinted in my brain.

For short distances, <30 feet, Bluetooth is pretty easy to use. Like the HC05 and HC06 modules. There is Bluetooth LE, too, but I have no experience with that.
Also the 433MHz radios. Though the ones that I have used are one way only.
Then there is Lora for long range, which I have zero experience with.
I've had a lot of success with the RFM69 radio transceivers on 433MHz (but much less success with LoRa transceivers for some reason). There's a load of information on the LowPower Labs website and their forums about their Moteino range of boards and the varieties of RFM transceiver modules that can be used with them. They also have their own library for the RFM modules. I've had much more success with their own RFM library as well.
And there is even LoRa devices for use in the 2.4Ghz band at data rates to match the NR24s.
