My advice fwiw is to buy a new (or used) decent quality rod and reel. If it turns out that you just can't get into Musky fishing, you can always sell it and usually recover a good percentage of your investment. And if it turns in to an addiction, you've got something that will serve you well, without thinking that you need to immediately upgrade.
If you buy something "cheap"...you're not going to enjoy using it...and since it's of low value you'll have a difficult time trying to sell it, if you decide to move up to something better or it turns out that Musky are just not for you. So even though you initially spent less, you end up eating the $$.
Just my experience when it comes to fishing gear...and frankly a lot of other things too..
I have run many businesses over the years, and this philosophy has always served me well.
