I stopped growing grape tomatoes. They're easy to grow but they're an indeterminate variety, and since they grow so fast they require a lot of pruning. I found a determinate variety of cherry tomato that grows so sturdy that it could potentially stand on its own without any trellis or cage until it starts fruiting, not willing to test it though.

I built a trellis using T posts, electrical conduit, and PVC pipe and it has worked extremely well.

It's basically this. Takes some work and some money but it was well worth it to me. I will have this for years and it performs much better than cages.

And yes, indeterminate tomatoes require pruning but it's well worth the trade-off to me to have tomatoes ripening all the time instead of all at once.
