Auto-Favorite tool?

Just wondering if there are any good alternatives to twitfox & followliker when it comes to auto-favoriting tweets in a specific niche.
Have been using my own python bot but no good for handling multiple accounts with different sets of niches.
Also, prefer service like twitfox (web), so I won't have to leave machines running 24/7 basically. Twitfox is a great service but $40 per month is abit hefty for this sole function I feel.. Anyone know of any decent options a bit less expensive or do I just need to shell out?

I created an auto-favorite tool, it's called Archie.co. I hope it works for you - it's cheaper than Twitfox.

I can confirm archie.co works pretty well. Been using it for a couple months. The only thing I don't like about it is I feel it could "unfavorite" faster or better. I've now got almost 30k favorites and I wish archie could help me lower that number.

Buy a bot, rent a VPS. Will work out cheaper than $40 per month

You can buy tool on fiverr. I think it's cheaper
