Unmanaged CentOS VPS required

Any recommendations would be appreciated:
Unmanaged CentOS VPS: 30GB SSD Storage, 4GB RAM, 2 vCPU, 3 IPv4 addresses
Hopefully looking to pay $25/month
Can I trust Regvps.com and also Libertyvps.net vps hosts? Any reviews, please?
Thanks

After 2 days using Regvps.com Switzerland vps, I knew they were the ones. Instant support, and if you can't get through to you by chat, I have never waited more than 10 hours to receive a reply by email!
They don't lie about their uptime. I have another plan with them and I've never had a downtime. Never in 8 months, going on!

Never had any problem with Regvps.com Switzerland vps - XenVps1 - $15/month, CPU 2хE5-2680, RAM 1GB, HDD 25GB, Bandwidth 1TB per Month, Location USA - Los Angeles, Germany, Switzerland, Russia.
My site is always up. I've never had any downtime. All in all, my experience has been great and I will definitely continue using their cheap hosting services.

If you are tired and frustrated of other hosts playing around with you, including me, I would highly recommend Regvps.com host for you.
Even the Security Issue is now under control. If you have questions about your account you get a response in almost a second.

I would recommend anyone to Regvps.com private vps Switzerland. Most everything I wanted to do just worked, and any problems I had were quickly solved by their self-support.
The customer service is prompt and always give me the information I need to make my website function the best.
