Go to lowendbox.com search for racknerd.com and find their annual plan for like $20-25. Use mailinabox. You will be ready in less than an hour all included and won't have to me try for a year.
But more broadly, any prepaid service is potentially an 'exit scam' and the point is to minimise your risk.
So in the end the price of the service (along with quality/value) is really the main consideration. Losing $20 at some point in a year is not much of a risk. I've used many providers, maybe using a bit of judgement, and I've only once come anywhere close to this, but even that seemed to just be a business failure and my account was sold but the replacement service was not as good.
