I think they are worth it. Here's 10 reasons I can justify expensive toys. They:
1. Are generally made of better, longer lasting, more durable and, most importantly to me, SAFER materials.
2. Have better motors and other moving parts in the case of vibrators and things like that. Thus will last longer and perform better than cheaper toys. Both this and #1 mean the toy will last longer!
3. Generally feel better during use. I've even found this to be true in the case of glass toys. My girlfriend has a cheapy glass piece that feels almost sticky to the touch and needs a lot more lube than our more expensive, better made pieces. More expensive silicone definitely feels better than cheap silicone or inferior materials! Better made toys are also usually a better shape. They also are less likely to have imperfections, especially the type of imperfections that can be felt (ie seams).
4. Usually look nicer and aesthetics are important to me. Maybe that's silly but I don't care.
5. Usually provide better quality vibrations. The vibrations from cheap vibrators just don't feel as good. Points 3-5 mean I will use the toy more than a cheaper one!
6. Are often "greener" meaning made of more environmentally friendly materials (!), made by companies with greener business practices, rechargeable, etc.
7. Are frequently, as mentioned above, rechargeable which saves expense of batteries and is much more convenient.
8. Are often backed by a MUCH better warranty and better customer service from the manufacturer than cheaper toys. This means, if the toy is defective or breaks (if it's not my fault), my money is less likely to be wasted!
9. Make me feel good about myself. I know this is materialistic and whatever, blah blah blah, but it's true. Spending money on myself once in a while, when I can responsibly afford it, feels good. I get to treat myself to something nice for going to work, school, putting up with assholes, working hard, being responsible.
