Do you have any good value hyper cardioid microphones you would recommend for indoor use?

I understand that they might not be great. I do want a proper stereo setup eventually. I'm glad to hear about your opinions as the built in mics are something I've not heard much about at all. Have you (or anyone else) got experience with these? seelectronics.com/sE1a_Stereo.html

I have been concerned with people being put off with sounds recorded on such a device. But when it comes to selling, I am a web developer/designer by trade and already have a platform together which will be open for others to sell sounds through it. I'm in a position where I want to learn so renting a device for a day here or or there doesn't appeal to me too much. But I do appreciate what your saying and it is worth thinking about.

All my experiences with Zoom are that the noise floor of their units are poor. The XLRs are good... But after hearing sound comparisons, I don't have much confidence in the Zoom stuff. Thank you for replying, your opinion is appreciated.

@robin This is a great response. Thank you. It's given me confidence that the Fostex is the way to go. I do appreciate the build isn't great. I'm thinking combined with a decent Portabrace custom bag (eventually) it will help with protecting the unit. Also, I'm glad you said about the Sony PCM-10... That is exactly the handheld I was looking at and am thinking that selling the Zoom H2 to put towards that is the way to go. Mono is my major concern, it's spot effects etc that I do want to concentrate on. And with the Sony I can do stereo with that... It's quiet noise floor that is important.

I learnt something from every response I got off this question. But yours covered most, and helped me. I have changed to getting a NTG-3 and looking into the Rycote gear as we speak. Thank you (and thanks to everyone else too!)
