We would normally recommend to use an inexpensive trainer at first and spend any money saved on a power meter for your bike. Stages are good value and straightforward to use.
Expensive indoor trainers have power meters built in, however we recommend to have a power meter on your bike, rather than just on your trainer (both are ideal). So you can use it for races.
Some trainers are direct drive, meaning you remove your back wheel to attach your bike to the trainer. They feel more realistic but they are not cheap.
Please do your research and look at some online group tests before you buy any trainer, simply searching for "which bike trainer" or "which power meter" on the internet will produce a wealth of opinion and advice for all abilities and budgets.
