I bought a garmin 510 because I was getting tired of using my phone as well...honestly, I love it. Its a very handy piece of equipment. I'd recommend a garmin to anyone.

Personally, I'd get some cheap bibs and jerseys off of chainlove or theclymb and splurge on the electronics. Yeah they might not be super cool and the chamois probably won't be the greatest, but electronics are more fun in my book. Then save cash on the side and when some nicer gear comes along at a marked down price, you can jump on it.
