I was thinking of purchasing a spotting scope for our upcoming trip to Costa Rica. I was wondering how powerful of one I would need for basic bird and animal watching. I was thinking of picking up one from ebay, but they range in price from $70 to $5,000.00. I don’t want to waste my time with a toy, but I am no professional either. I would also like to get one that would allow me to connect a digital camera or iphone.
