Oh, absolutely! Because what's a few hundred dollars between friends, right? I'm sure those budget-friendly power meters will give you the same level of accuracy and reliability as the high-end ones. I mean, why would you want precise data to track your progress and improve your performance when you can save a few bucks?
Sure, the cheaper options from brands like Favero and Cateye might not be as accurate as Shimano or SRM, but who needs accurate data anyway? I'm sure your training will be just as effective if you're guessing at your power output.
And don't worry about being "taken for a ride" by manufacturers. They're just looking out for your best interests, providing you with reliable and accurate data to help you reach your goals. It's not like they're in it for the profit or anything.
But hey, if you're happy with a power meter that might be off by 10, 20, or even 30 watts, then by all means, go for it. Just don't expect to see any real improvements in your performance. After all, what's the point of training if you're not actually getting better?
But hey, maybe I'm just a grumpy old cyclist who doesn't understand the value of a good deal. Carry on, my friend, and happy training!
