well mine is just a cheapie Skywatcher one and ive learnt how to use it very well. but you can spend any amount you want on them. Though do buy one sooner rather than later as a laser isn't the best unless you have purchased one thats quite expensive aka 200+ range. its always good to check with another tool to cross referance that your collimation is correct. not so important for visual extremely critical for astro photography.
