Yeah a fixed bridge is the way to go on this budget. Try out the guitar thoroughly, just make sure the hardware on the guitar is decent and the amp you play through is also an important part of your tone. 18-20k is a decent budget, buying second hand is also a nice option and you get a better instrument at a lower price.
Guitar: Ibanez S570B
