Ultimately, you do what you feel comfortable, and hey, if you haven't bought one yet, maybe it's because you don't feel comfortable or really don't want one (maybe you have enough fun with your bikes as it is, the simplicity of just riding a bike is very hard to beat). It's interesting to note that I swear I've had loads of fun out a freebie old English 3-speed, possibly more than someone who rides an multi-thousand dollar bike at times. However, I do admit bikes are my weakness, and I've only ever regretted buying one frame off ebay -but loved all my other bikes -from freebies to $1,500 bikes.

The true enjoyment is in the bike and riding it, not in the dollar amount spent.

However, I do think there is something to be said for if you can afford it, and you know you'll get enjoyment out of it, do it -it sounds like you can and that you enjoy your biking. Life's too short. There is no doubt in my mind you get enjoyment out of using a quality product.

Happy ridin'!
