$140 for a refurb 1030 or $380 for a Roam ?. 1030 all the way. It'll likely never have an issue again.
If buying new and for your limited needs of larger text, I'd say get a Roam.
FWIW, I've never had screen glare issues on my 1000 or 1030, while I could not see the turn-by-turn directions on my Bolt, which are white text on black background. It was unreadable while wearing sunglasses. TBT generally is much better on a 1030.
If you end up not happy with the 1030 you could e-bay it for what you paid Garmin.
